Objectives: The purpose of this study was to examine whether adding homocysteine (Hcy) to a model based on traditional cardiovascular disease (CVD) risk factors improves risk classification.
Background: Data on using Hcy to reclassify individuals in various risk categories beyond traditional approaches have not been adequately scrutinized.
Methods: We performed a post hoc analysis of the MESA (Multi-Ethnic Study of Atherosclerosis) and NHANES III (National Health and Nutrition Examination Survey III) datasets.

Introduction: Mammography can reduce breast cancer mortality through routine screening. We tested an intervention to increase re-screening in a county program.
Methods: The program requires enrollment before screening.
Background: While screening has been demonstrated to reduce breast cancer mortality, the optimal screening interval is unknown. We designed a study to determine the risk of an advanced breast cancer diagnosis by varying the interval between mammograms.
Methods: We reviewed a single state's mammography records of women diagnosed with breast cancer between 1994 and 2002.
Background: While reminders can promote cancer screening in primary care, little is known about the potential interaction between multiple reminders.
Methods: We conducted a randomized controlled trial to compare the effect of combined Pap smear plus mammogram reminders and mammogram-only reminders among 2471 women 40 years of age or older enrolled in a health maintenance organization serving a predominantly Medicaid-eligible population. Reminders included both a mailed letter for the woman and a medical record prompt.
Objective: To develop a longitudinal model to characterize the delivery of mammography services using repeated observations of mammography referral rates during a randomized controlled trial (RCT) of physician mammography reminders.
Data Sources/study Setting: Administrative records of a health department and observational data on mammography appointment scheduling.
Study Design: The design was a longitudinal study of month-specific referral rates during a 1-year RCT.
